Tornado Warning

Tornado warning

A tornado warning is a public warning that is issued by national meteorological services for an area in the path of a tornado, or a severe thunderstorm capable of producing one, and advises individuals in that area to take cover. They are often issued based on detection of rotation in a thunderstorm by a Doppler weather radar which can provide earlier warning. Modern enhancements to radar can also allow confirmation and tracking of a tornado by the presence of a debris signature. They are also issued based on reported visual sighting of a tornado, funnel cloud, or rotating wall cloud by weather spotters, the public, law enforcement, or local emergency management. In some cases, radar detection may be limited or hindered by distance, terrain, or outright unavailability, making such ground truth crucial and complementary. Likewise, a tornado may be obscured by heavy precipitation, occur at night, or both, making spotting extremely dangerous or impossible.
